I went with mates and we ended up talking to loads of folk who were travelling themselves. I thought about doing something similar by myself this year but decided against it cos as Padre says it's just better with your mates. Had a fantastic time and even the travelling by train was ace, cos we were mostly in a compartment ourselves, just relax and have a laugh and a few beers.
And to echo Padre again, Bratislava is highly recommended. I've never seen women like that in my life. The main street with pubs and restaurants was like a supermodels catwalk. The place itself is lovely too.
We're going to Barcelona then on to Nice, Genoa, Bergamo, Verona and Munich this year. Travelling round last year was easily the best holiday i've had, and i'd thoroughly recommend it to you.
